SEALING DEVICE FOR JARS.

Application filed `May 27, 1924. Serial No. 716,143.

This invention relates to improvements in receptacles and cover fasteners therefor, used in preserving food or the like but is not limited to such use.

An important object of this invention is to provide a device of the above character in which the cover fastener is carried by the bail. t

Another object of this invention is to provide the device of the above character in which the cover fastener is capable of being conveniently and expeditiously applied or removed from the cover and which, when applied, will cause the cover to hermetically seal the receptacle.

A further object of this invention is to provide a device of the above character which is simple in construction and easy to manufacture, durable and eiiicient in use, and one which can be placed upon the market at a reasonable cost.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a side elevation of the cover and lock,

Figure 2 is another side elevation taken at a rigl'it angle to the elevation illustrated in Figure 1,

Figure 3 is a vertical. sectional View taken on line 3 3 of Figure 2 showing the cover and sealing gasket in position,

Figure 4 is a plan view of the device, and.

Figure 5 is a fragmentary sectional view showing the sealing gasket applied and the cover removed.

Referring to the details of the drawings, the numeral 10 designates a receptacleor other vessel provided with a closure or cover 11 and with a bail 12 pivotally connected thereto adjacent the upper end thereof.

The inner circumference of the receptacle 10 tapers toward the bottom while its outer circumference is substantially the same throughout its length. This tapering of the inner circumference of the receptacle not only permits preserved foods, such as fish. meats, or the like to be easily removed, but provides for the ready cleaning of the same. With most of the receptacles now on the market, foods of the above character must be broken to pieces to be removed, While in som-e instances the receptacle itself must be destroyed to remove its contents. The receptable is provided near its upper end with an external gasket or seal supporting shoulder 13 which is adapted to be under-cut as shown at 14 in Figures 3 and 5. The shoulder 13 is adapted to receive a gasket 15 formed of rubber or other suitable material which is preferably circular in cross section. i

rihe low-er edge of the cover 11 is provided with an annular curved groove 16, which bears directly upc-n the gasket 15 to force it` into the under-cut portion 14- of the shoulder 13 when pressure is applied to the cover, as shown in Figure 3. rIihe upper surface of the cover 11 is preferably convex and a rectangular boss 17, is centrally located upon the uppermost portion of said upper surface of the cover. This boss 17 is formed with transverse grooves 18 to provide projections or teeth 19.

As stated above, the receptacle 10 is provided with a pivotally connected bail 12, the bail having a central portion 2O thereof, bent substantially in the form of an inverted U. A spring lock member 21 is secured to the central inverted U-shapcd portion 2O of the bail by bending or looping one end of the lock member over the bail as at 22 to form a pivot for the same. The sides of the central inverted U-shaped portion ofthe bail are adapted to act as stops to prevent lateral movement of thc spring lock member.

The spring lock member 21 is preferably formed of a strip of sheet metal bent near its center to form a V, one side of said V being shorter than the other side. The short side 23 of the V is looped atits end to form a bail engaging loop 22 while the end 24 of the long side of the V is shaped to provide a finger engaging portion 25. The long side of the V between the bend or elbow 26 and linger engaging end 25 is formed with corrugations 27 adapted to engage the projections or teeth 19 when the cover is to be locked in position on the receptacle. The bend or elbow 26 near the center of the V- shaped spring lock member is adapted to act as a fulcrum to force the cover in position.

In operation, the bail 12 is swung to an upright position and the bend or elbow 26 of the spring lock member 21 is engaged with any one of the transverse grooves 18 of the rectangular boss 17. By applying a downward pressure upon the end 25 of the spring lock member 21, the bail 12 is swung be yond the center of the member 21, causing the side 24C of said member 2l to exert pressure upon the cover 11.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the saine, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claim.

Having described `my invention, I claim:

A receptacle comprising a body having a side wall, the said body being provided at the exterior of its side wall and at its end with a shoulder having an outwardly in- (lined surface disposed approximately transversely across the outer portion of the side wall of the body, the inner portion of the side wall of the body having an outer lindercut surface disposed approximately at a right angle to the adjacent sairface of the shoulder and approximately alined with the median longitudinal dimension ofv the wall o the body, a compressible gasket resting upon the inclined surface of the shoulder and hugging against the undercut surface of the side wall, a cover having a peripheral iiange provided at its lower edge with an inwardly chamfered surface adapted to rest upon the outer portion of the gasket, the inner surface of the flange being spaced outwardly from the upper edge of the undercut surface oic the side wall of the body, a bail pivotally connected with the body and adapted to Swing over the cover, and a spring member connected with the bail and adapted to bear against the cover whereby the chaniiccred surface at theV edge of the iiange of the cover forces the gasket inwardly against the undercut surface of the side wall of the body. Y

In testimony whereof, I have ailixed my signature.

ROBERT EDVVARDSON.
